  1. Simple Plagiarism Detection Duy Nguyen Ramakrishna Bhandage

  2. Problem Definition • Implement a simple application to determine if a suspect text file is plagiarized by comparing it with the set of corpora in the given library (set of text files). • The suspect file and corpora are in simple text format (*.txt) • Algorithms used to detect the plagiarism:  • LCSS • KMP • Rabin-Karp • Compare the performance of algorithms used in the implementation

  3. Major Components • SimplePlagiarism: • detect() • getRunningTime() • onAlgorithmStarted() and onAlgorithmEnded() • SimplePlagiarism subclasses: • LCS: getLCSSLength() • KMP:  • tableBuild() • match() • RabinKarp:  • match()  • Utility: • getParagraphs() • getSentences() • normalizeText()

  4. Major Components (cont.)User Interface
